Could you provide the make and model of your recorder?
Generally if there is a problem with a timer, the Lite-On recroder will leave the timer intact, but with a warning '!' (at least on the LVW-5045). If this is the case, highlight the recording and there should be a small description of the error at the bottom. An example of an issue includes attempting to record using Video CD mode while a DVD+RW is present in the drive. :doh:
Finally, just be sure the correct time & date are set. :rolleyes:
